Inquiry about an LPG run H3..
 

Just new to this forum & hope anyone could help me. Was planning to get me one H3 2009 brand new (could you believe it?) considering it is a dead brand but i just gotta have it. I know the V8 Alpha could be quite thirsty and i was just wondering if it could be converted into LPG? Fuel prices where i stay is crazy.

(I have done a little research on the possible engine valve damage it can do and using "flash lube" or some "upper cylinder lube kit" for reducing wear on it.) Yep, I could go to an official LPG service center to ask but I prefer to ask the "hummer guys" first.

Any infos are greatly appreciated!

I haven't heard of one, doesn't mean there isn't though. Sounds like a cool idea, do it and post a writeup on the results!

I haven't heard of any H3/H3T on LPG.

But I have read about an H3T that had a compressed natural gas conversion. Here is the link:

GoNatGas | We believe that Natural Gas Vehicles (NGVs), are cleaner, cheaper, and a lot more fun to drive than gasoline-fueled vehicles.

i dont know where you are living williamramez but on the german forum there is quite a lot of threads on it.

here in portugal LPG is pretty popular but Hummers are rare. I am planning to do the same and get LPG in my hemmer.

in Holland about 50% of all cars drive on LPG and most of the thirsty USA cars are on LPG


good luck

I'm looking at taking my Hummer H3 back home when I leave the Emirates and return to UK.

Fuel is very expensive in UK with LPG about half the price. The government offers a grant I believe that pays part of the cost of the LPG conversion, leaving me with perhaps USD2500 to pay.

There are places in the UK that do the conversion, so its definitely possible to do it on H3. Generally you'd end up with a dual-fuel system, and so you need 2 fuel tanks. They can either fit the LPG tank in the cargo area at the back, or replace the existing hummer 87litre fuel tank with a dual tank (eg 65 litre LPG + 20 litre petrol).

The main issue I've looked at is whether the price differential between LPG and unleaded petrol will remain (and hence justify the cost of the conversion). When unleaded petrol first came in it was cheaper than leaded petrol (less tax to encourage take up of unleaded). But once everyone was onto unleaded, the tax was hiked. I imagine as more move onto LPG, the tax differential with unleaded will shrink.

Thanks for the info joostie62. il try to check them out. i live in Manila (philippines) by the way where gas prices and street roads are stupid.. making our H3's greener might be a cool idea..

- Great insights Rajul_Al_Hummer! Yep, prices of the LPG are almost half of what unleaded petrol costs here and somehow the thought occured to me regarding future price hikes.

if i get to buy the H3 sooner (or later) i intend to use it daily & so making them run on the greener side would not only make it economical but environmental friendly as well.

As for the added tax, i think i am safe to say i wouldn't worry about that for maybe the next 6-8years or so.. i'd be doing my countrymen honor telling you how our funked-up government manipulate taxes on petrol (& most other things) but i'd be boring you guys out to death..that's why hybrid/electric cars are still rarely found running around the streets in manila..

I have located an LPG station service center very near my place (Manila Autogas) and i plan to visit them soon for inquiries.

just a little bothered by the assurance of an H3 engine or engine valves (so they say) not clunking out because of the conversion. Cost for the conversion is not an issue.. its the longevity of an LPG run engine that concerns me most...

checked it out & can't even decipher how to enter the site. Translator Pleez!! LOL!

Hi williamramez,

I am the owner of hummerforum.de. After registration, you can switch to English language, but this won't translate the contents ;-)

Converting to LPG is very popular here. The price for LPG is about half of the price for fuel. This is due to lower tax, which is based on a law that lasts until 2018. So after 2018 the price might rise. I am almost sure it will...

Most important aspects:
- LPG consumption is appr. 10% higher than driving with Fuel
- Valve shafts of every engine model (I5 or V8) will not stand LPG for ever. You can drive until they need to be replaced.
- You will need flash lube
- Never heard of the fuel tank being replaced for a LPG or a smaller Fuel Tank
- The LPG tank is either in the trunk or beneath it, then the exhaust has to be replaced as well
- Converting to LPG here is about 2,500€ to ~5,000€
- Often heard of warning messages caused by "not consuming fuel", when driving with LPG
- In some parking garages cars with LPG are not allowed
- But: Most LPG H3 driver seem to be very pleased with their decision...

I did not and I will not switch to LPG because I don't like to add possible causes for engine wear or additional components that need maintenance or might fail.

I hope this helps a little ;-)

hi achim1000! Scary sh#t! i just found an new H3 I-5 3.7L engine selling near our place (yep, there are still a handful selling new ones where i live) and I might just get that.

flashlube or no flashlube im caught between a rock & a hard place taking a risk jeopardizing the engine though i was assured it won't but im pretty sure the 3.7L is more fuel friendly than the Alpha.

thanks for the info by the way i can now check your site..:)
